Specification of Letters Patent.

Patented Sept. 30, 1919.

Application filed January 25, 1818. Serial No. 218,700.

To all whom t may concern:

Be it known that I, P1-11L1rrn DE CLAMECY, a citizen of the United States, and resident of Boston, county of Suffolk, and State of Massachusetts, have invented certain new and usefulV Improvements in Type-Writing Machines, of which the following is a speci` ication.

The object of the invention is to provide a lightweight typewriting machine containing the usual groups of mechanisms found in the accepted standard typewriting machinos, and to simplify the construction of the machine and materially roducethe number of parts in order to lessen the cost of manufacture and produce a small portable machine.

In the drawings, Figure 1 is a longitudinal vertical sectional view ofthe machine, parts of the operating mechanism being shown in side elevation;

Fig. 2 a horizontal sectional view of the machine;

Fig. 3 a plan view thereof;

Fig. 4 a transverse sectional view on the line IV-IV of Fig. 2;

Fig. 5 a transverse sectional view taken through the keyboard and showing one bank of keys;-

Fig. 6 a detail front elevation, with parts broken away, of 'the ribbon vibrating mechanism;

Fig. 7 a similar view showing the ribbon vibrator mechanism in side elevation;

Fig. 8 a transverse sectional view on the line VIII--VIII of Fig. 6; and

Fig. 9 a detail view of the means for raising the platen carriage to ,its different caseshift positions.

Referring to the various parts by numerals, 1 designates the main frame of the machine which is preferably formed of light rigid material such as aluminum, said frame constituting a keyboard part 2, ribbon-reel supporting partsnand the type-bar receiving part 4 located between the ribbon-reel supports and the rear Wall 5. The usual pivot wire (j furthe type-bars extends transversely of the type-bar receiving portion of the main frame, and on said ivot wirethe type-bars 7 are mounted. aid bars normally extend forwardly from their pivots and are provided with type headsA 8 `which ,rest on the type support` 9 of the main frame, suitable cushioning means being provided to receive the type heads when they return to their normal at-rest positions. Mounted on the keyboard frame part 2 are a series of upwardly extending guide tubes 9, said tubes being arranved in parallel transverse lines and constltu'ting banks. The tubes 9 are of different heightspthe lower ones being arranged in the first bank and the highest ones being in the rear bank. In cach tube is arranged a vertically reciprocable key rod 10 which carries at its upper end a luger key 11. The keys are arranged at a uniform distance above the upper ends of the guide tubes in order that the key stroke will be uniform for the different banks. The lower end of the key rod, within the frame of the machine,A is provided with a head 12 which serves as a limiting stop for the upward movement of the key and also carries a 'transversely extending horizontal pin '1:3 which enters the upper end of a curved slot 14 formed in a type-bar operating lever 15. The levers 15 for cach bank of keys are pivoted upon a common pivot rod 16 which extends horizontally and transversely across the keyboard part of the main frame. The slotted portion of the levers 15 extend forwardly and upwardly so that the slot is obliquely arranged with respect to the key rod. Upon the depression of a key the upper slotted portion of the key lever is swung forwardly and downwardlv, the portion of the lever below the pivot 16 being forced rearwardly and upwardly. Connected to the lower end of each of the type-bar operating levers is a rearwardly and upwardly extendingv link 17, the rear end of which is connected to the type-bar near the pivot thereof, as indicated at 18 in Fig. 1. It is manifest that by depressing a key the connected link 17 is'thrust upwardly and rearwardly, thereby swinging the type-bar upwardly to bring the type head to the printing point. Connected t0 the lower end of each of the type-bar operating levers 15 is a tension spring 19. The lower ends of these springs are connected to a horizontal plate 2O which rests on the base of the frame and is adapted to moveforwardly and rearwardly in guides 21 formed on the sides of `the main frame as shown clearly in Fig. 2. This tension plate 20 may be adjusted 'orwardly or rearwardly lto vary the tension of the springs 19, by

The rear end of each type-bar is extended upwardly and rearwardly to l'orrn a nniversal bar operating cam 25, Extendin ,transverse'l of the machine directly he ow the pivot Wire 6 is a universal bar 26 on which is mounted a series of roliers 27, one roller for each type-bar. lThe universal bar operating cams -25 of the type-bars are adapted to engage said rollers to thereby depress ,the unircrsal bar. The universal bar, at each 0f its ends, is provided with a. depending guide Jin 28 which fits 'within a rigid guide tube Z mounted on the base of the machine. Surrounding the guide pin 28 is a spring 30 which normally maintains the universal har in its up er osition but allows it to be depressed throng 1 the action o l .the rains Through the operation of the universal har the escapernent mechanism and ribbon vibrating and feeding mechanism are operated.

The' carria e bed comprises two transyersely exten' ing tracks l and 32 rigidly f connected together by depending 7olres .33.

The tracks are horizontally groove on their adjacent faces to receive ball bearings 3.4 which are adapted to be engaged by track surfaces formed en the forward and rear of the carriage base plate. The end 'foires of the carriafre bed are provided with ependi posts 3 which are beveled and fit Within corresponding beveled guidexvays 36 formed on the inner surfaces of the sides of' the main frame, as shown clearly in Fig. 2. 1ihen the carriage bed is in .its lower normal position the tracks 31 and 32 rest o n t e upper edges. ofthe machine frame, as s'mwn yIn l. To lift the carriage bed, and'l the c arria e mounted thereon, for the several ease-ShiV t positions. two. pai 's of ec- Qentrics 3l? and 38 are wulfyd'l @se ec- Centrics engage` a. lg'iterallyextendn ooiI 39 of the 3'5, asshown clearly in FQS- 1 and 2 j the drawings. The eccentrics 37 are Sller iu, diameter than .the ecccutrics 38 so that. one ccentrics. are adapted! to move the carriage to one case-shift position, the other .Set iug' adapted temere *heierto othery case-shift posltion. The .air of escentrls 38 are mounted upon a Ewrioutal. shaft. 3.9 llrnaled. 11i .Suitable carin s 4inthe Sides of' thev amr frame Ty y ein@ tha postj, ecurcd to said it' near ealeud. thfeofis a crank arm 40 loll il and fbriterdhf'as armis: a fnrvirdly er en einen@ k PP n r1 whose forward extending operating nid end is connected to the lower end of one of the operating lovers 15, said 1everbe-ngopnatively connected to a shift key 4Q, as shown clearly in Fig. 2. Upon the depression of the shift key 42 the operating rod 41 is thrust upwardly and rearwardly, thereby rotating the shaft 39 and causing the cccentrics $8 to move the posts 35 and the connected carriage hed upwardly to the upper-case position.

The occentrics 37 are mounted upon a sectional sleeve 43 which surrounds the shaft 39. ThisI sleeve is divided near its ends, the sections being connected together by means of the crank 44 `as clearly shown in Fig. 9, said crank bridging the crank on the shaft 39, as clearly shown in said figure. Connected to each crank 44 is an operating rod 45 which extends forwardly to an operating lever 15, said lever being operatively connected to a. sh'ift key 46. Ti is manifest that upon the depression of the shift key 4G the sleeve 49| will be rotated and the connected cccentrics 37 caused to lift the carriage hed and the platen carriage thereon to the intermediate case position. The platen shift keys are provided with tension springs 19 to return the keys and the eccentries to their normal at-rest ositon, and said springs are conneeted o the tension .plate precisely as described With respect to the type-bar operatinlevers.
